Description

Frequency hopping information determination method, device, terminal and network equipment

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on November 8, 2023, with application number 202311482213.8 and application name “Frequency Hopping Information Determination Method, Device, Terminal and Network Equipment”, all contents of which are incorporated by reference in this disclosure. Technical Field

[0002] The present disclosure relates to the field of communication technology, and in particular to a method, apparatus, terminal, and network equipment for determining frequency hopping information. Background Art

[0003] To address the coverage, latency, and capacity issues of uplink transmission in the time division duplex (TDD) mode, non-overlapping sub-band full duplex (SBFD) will be studied. This involves dividing the frequency domain resources into multiple non-overlapping sub-bands, with the uplink and downlink frequency domain resources located in different sub-bands, referred to as sub-band full duplex.

[0004] Since the frequency domain resources (uplink subband) used for uplink transmission on SBFD symbols are less than those on full uplink symbols, for multi-slot uplink transmission that spans SBFD symbols / time slots and full uplink symbols / time slots, the base station can ensure that the frequency hopping position is within the uplink subband range. However, the base station implementation complexity in this case is high and the frequency hopping gain is limited.

[0155] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0156] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

The terminal can determine the frequency hopping indication and / or frequency offset on the SBFD symbol and the frequency hopping indication and / or frequency offset on the uplink symbol respectively according to the frequency hopping indication and / or frequency offset indicated by the network device. The frequency hopping related information can be used to indicate whether frequency hopping is enabled, for example: the frequency hopping related information sent by the network device includes 1, indicating that frequency hopping is enabled; the frequency hopping related information sent by the network device includes 0, indicating that frequency hopping is not enabled. The opposite is also possible, and the specific indication method is not limited here.

[0165] It should be noted that the SBFD symbols in the embodiments of the present disclosure may also be replaced with SBFD time slots, wherein the SBFD time slots are time slots in which all or part of the symbols are SBFD symbols, and the uplink symbols may also be replaced with uplink time slots, that is, the terminal determines whether to enable frequency hopping and / or the frequency offset of frequency hopping in the SBFD time slot based on the frequency hopping related information indicated by the network device, and determines whether to enable frequency hopping and / or the frequency offset of frequency hopping in the uplink time slot. The embodiments of the present disclosure may be applied to multi-slot PUSCH transmission, PUSCH repeated transmission, and / or PUSCH configuration transmission, etc., and the specific application scenarios are not limited.

[0166] In an embodiment of the present disclosure, a terminal can determine frequency hopping parameters for two time slot types, namely, SBFD time slots and uplink time slots, based on a set of frequency hopping related information indicated by a network device. This reduces the implementation complexity of the network device and increases the flexibility of the frequency hopping configuration and the frequency hopping gain without increasing the signaling overhead.

[0167] As an optional embodiment, the terminal determines, according to the frequency hopping related information, whether to enable frequency hopping on the SBFD symbol and whether to enable frequency hopping on the uplink symbol, including at least one of the following:

[0168] If the frequency hopping related information indicates that frequency hopping is not enabled, frequency hopping is not enabled on the SBFD symbol, and frequency hopping is not enabled on the uplink symbol;

[0169] If the frequency hopping related information indicates that frequency hopping is enabled, frequency hopping is enabled on the uplink symbol, and whether frequency hopping is enabled on the SBFD symbol is determined according to the first information.

[0170] In this embodiment, the terminal may determine whether to enable frequency hopping on the SBFD symbol according to the frequency hopping related information sent by the network device.

[0171] Optionally, the first information includes at least one of the following:

[0172] Frequency domain resource configuration information on the SBFD symbol; for example, the starting resource block (RB) and / or the number of RBs configured on the SBFD symbol;

[0177] Optionally, the determining, according to the first information, whether to enable frequency hopping on the SBFD symbol includes at least one of the following:

[0178] (1) The first information includes: frequency domain resource configuration information on the SBFD symbol and / or frequency domain resource allocation information on the SBFD symbol; if the number of resource blocks (RBs) corresponding to the frequency domain resources allocated or configured on the SBFD symbol is determined to be greater than or equal to a first value based on the first information, frequency hopping is not enabled on the SBFD symbol; if the number of RBs corresponding to the frequency domain resources allocated on the SBFD symbol is less than or equal to the first value, frequency hopping is enabled on the SBFD symbol; if the first value is related to an uplink subband size, the first information also includes uplink subband information;

[0179] This embodiment is an embodiment of determining whether frequency hopping is enabled on the SBFD symbol based on the frequency domain resource configuration information or allocation information on the SBFD symbol. If the number of RBs corresponding to the frequency domain resources allocated or configured on the SBFD symbol is greater than (or greater than or equal to) the first value K1, frequency hopping on the SBFD symbol is not enabled; otherwise, frequency hopping on the SBFD symbol is enabled. The first value can be a predefined parameter, for example: the first value is the number of RBs contained in the uplink subband / 2, or the first value is a parameter configured by the network device. Optionally, if the first value is related to the uplink subband size, the first information also includes uplink subband information.

[0180] It should be noted that the greater than or equal to in the embodiment of the present disclosure may include “>” or “≥”, and the less than or equal to in the embodiment of the present disclosure may include “<” or “≤”. For example, if the first value is K1, if the number of resource blocks RBs corresponding to the frequency domain resources allocated or configured on the SBFD symbol is ≥K1, frequency hopping is not enabled on the SBFD symbol; if the number of RBs corresponding to the frequency domain resources allocated on the SBFD symbol is <K1, frequency hopping is enabled on the SBFD symbol. Alternatively, if the number of resource blocks RBs corresponding to the frequency domain resources allocated or configured on the SBFD symbol is >K1, frequency hopping is not enabled on the SBFD symbol; if the number of RBs corresponding to the frequency domain resources allocated on the SBFD symbol is ≤K1, frequency hopping is enabled on the SBFD symbol.

[0181] (2) The first information includes: frequency domain resource configuration information on the SBFD symbol and / or frequency domain resource allocation information on the SBFD symbol, and uplink subband information; if the frequency domain position of each hop determined based on the starting RB of each hop in the two hops is within the uplink subband range indicated by the uplink subband information, frequency hopping is enabled on the SBFD symbol; if the frequency domain position determined based on the starting RB of any of the two hops is outside the uplink subband range, frequency hopping is not enabled on the SBFD symbol;

[0182] This embodiment determines whether to enable frequency hopping on an SBFD symbol based on uplink subband information, frequency domain resource configuration information on the SBFD symbol, and / or frequency domain resource allocation information on the SBFD symbol. If the frequency domain position of each of the two hops determined by the calculation formula for the starting RB is within the UL subband range, frequency hopping on the SBFD symbol is enabled; otherwise, frequency hopping on the SBFD symbol is not enabled.

[0183] (3) The first information includes frequency domain resource configuration information and / or frequency domain resource allocation information on the SBFD symbol, and frequency offset information of frequency hopping; if the frequency offset between the two hop starting RBs is greater than or equal to a second value, frequency hopping is enabled on the SBFD symbol; if the frequency offset between the two hop starting RBs is less than or equal to the second value, frequency hopping is not enabled on the SBFD symbol;

[0184] This embodiment determines whether frequency hopping is enabled on an SBFD symbol based on frequency offset information for frequency hopping, frequency domain resource configuration information on the SBFD symbol, and / or frequency domain resource allocation information on the SBFD symbol. If the actual frequency offset (offset) between two starting RBs of a hop, determined according to a calculation formula for the starting RB, is greater than a second value, frequency hopping is enabled on the SBFD symbol; otherwise, frequency hopping is not enabled on the SBFD symbol. The second value may be a predefined parameter, for example, the second value is the number of RBs included in the uplink subband / 2, or the second value is a parameter configured by a network device.

[0185] It should be noted that the greater than or equal to embodiment of the present disclosure may include “>” or “≥”, and the less than or equal to embodiment of the present disclosure may include “<” or “≤”. For example, the second value is the threshold value K2. If the frequency offset between the two-hop starting RBs is ≥K2, frequency hopping is enabled on the SBFD symbol. If the frequency offset between the two-hop starting RBs is <K2, frequency hopping is not enabled on the SBFD symbol. Alternatively, if the frequency offset between the two-hop starting RBs is >K2, frequency hopping is enabled on the SBFD symbol. If the frequency offset between the two-hop starting RBs is ≤K2, frequency hopping is not enabled on the SBFD symbol.

[0186] (4) The first information includes: frequency domain resource configuration information on the SBFD symbol and / or frequency domain resource allocation information on the SBFD symbol, uplink subband information, and frequency offset information of frequency hopping; if the frequency domain position of each hop determined according to the starting RB of each hop in the two hops is within the uplink subband range indicated by the uplink subband information, and the frequency offset between the starting RBs of the two hops is greater than or equal to a second value, frequency hopping is enabled on the SBFD symbol; if the frequency domain position determined according to the starting RB of any one of the two hops is outside the uplink subband range indicated by the uplink subband information, and / or the frequency offset between the starting RBs of the two hops is less than or equal to the second value, frequency hopping is not enabled on the SBFD symbol.

[0187] This embodiment determines whether frequency hopping is enabled on an SBFD symbol based on uplink subband information, frequency hopping frequency offset information, frequency domain resource configuration information on the SBFD symbol, and / or frequency domain resource allocation information on the SBFD symbol. If both conditions are met: the frequency domain position of each hop determined based on the starting RB of each hop in the two hops is within the uplink subband range, and the frequency offset between the starting RBs of the two hops is greater than or equal to a second value, then frequency hopping is enabled on the SBFD symbol; otherwise, frequency hopping is not enabled on the SBFD symbol.

[0188] As an optional embodiment, the method further includes:

[0189] Determine the starting RB position of each of the two hops based on the first starting RB position indicated by the frequency domain resource allocation information or configuration information on the SBFD symbol and the frequency offset indicated by the frequency offset information of the frequency hopping; determine whether the frequency domain position of each hop is within the uplink subband range indicated by the uplink subband information based on the RB length indicated by the frequency domain resource allocation information or configuration information on the SBFD symbol and the starting RB position of each hop.

[0190] In this embodiment, for the above-mentioned method (2) or method (4) of determining whether frequency hopping is enabled on the SBFD symbol based on the first information, it is necessary to first determine that the frequency domain position of each hop determined by the starting RB of each hop in the two hops is within the uplink subband range. Specifically, the starting RB position of each hop can be calculated based on the first starting RB position indicated by the frequency domain resource allocation information or frequency domain resource configuration information on the SBFD symbol.

[0191] As an optional embodiment, the method also includes: determining the starting RB position of each of the two hops based on the first starting RB position indicated by the frequency domain resource allocation information or configuration information on the SBFD symbol and the frequency offset indicated by the frequency offset information of the frequency hopping; and determining whether the frequency offset between the starting RBs of the two hops is greater than or equal to the second value based on the starting RB position of each hop.

[0192] In this embodiment, for the above-mentioned method (3) or method (4) of determining whether frequency hopping is enabled on the SBFD symbol based on the first information, it is necessary to first determine whether the frequency offset between the starting RBs of the two hops is greater than or equal to the second value. Specifically, the starting RB position of each hop can be calculated based on the first starting RB position indicated by the frequency domain resource allocation information or frequency domain resource configuration information on the SBFD symbol, thereby determining the frequency offset between the starting RBs of the two hops.

[0193] Optionally, determining a starting RB position of each of the two hops according to the first starting RB position indicated by the frequency domain resource allocation information or configuration information on the SBFD symbol and the frequency offset indicated by the frequency offset information of the frequency hopping includes:

[0194] Determine the starting RB position of each of the two hops according to the first starting RB position indicated by the frequency domain resource allocation information or configuration information on the SBFD symbol, the frequency offset indicated by the frequency offset information of the frequency hopping, and the second information;

[0195] The second information includes at least one of the following:

[0196] The number of RBs included in the BWP;

[0197] The number of RBs contained in the uplink subband;

[0198] The timeslot number where the multi-slot transmission occurs;

[0199] The number of the SBFD symbol within the time slot range where the multi-slot transmission is located;

[0200] The number of the uplink symbol within the time slot range where the multi-slot transmission is located;

[0201] Number of repeated transmissions;

[0202] The relative number of the time slots in which the multi-slot transmission occurs;

[0203] SBFD configuration period number;

[0204] The number of the time division duplex (TDD) configuration period.

[0205] In this embodiment, the starting RB position of each of the two hops can be calculated using the following formula 1 or formula 2:

[0206] Formula 1:

[0207] in, It is calculated The starting RB in the time slot, Indicates the current time slot number, which is the time slot number of the multi-slot transmission; RB start The starting RB in the uplink BWP, RB offset is the frequency offset value between two hops (in PRB units); Indicates the size of the uplink BWP (i.e., the number of RBs included in the BWP). start and RB offset It is the value indicated in the frequency domain resource allocation information or configuration information on the SBFD symbol, and can be determined by the frequency domain resource allocation field in resource allocation type 1.

[0208] Formula 2:

[0209] in, Indicates the size of the uplink subband (the number of RBs contained in the uplink subband).

[0210] The starting RB position of each hop can be calculated using either Formula 1 or Formula 2. For Formula 1 and Formula 2, the frequency domain resource allocation (including the starting RB and the number of RBs) for different symbol types can share the same frequency domain resource indication information / frequency domain resource configuration information, or can be configured or indicated separately, or determined separately.

[0211] An example of a method for separately determining frequency domain resource allocation for different symbol types is to share frequency domain resource indication information and determine the starting RB position for full uplink and SBFD symbols based on different interpretation rules. For example, the starting position for a full uplink symbol is referenced to the starting RB of the uplink BWP, while the starting position for an SBFD symbol is referenced to the starting RB of the uplink (UL) subband.

[0212] Optionally, in order to solve the problem that when a SBFD configuration period only includes one SBFD time slot and / or a TDD configuration period only includes one full uplink time slot, the actual determined RB start Only one value, that is, frequency hopping cannot be achieved. To solve this problem, we can consider replacing the above formulas 1 and 2 with Replaced with the relative number (index) within different time slot types, such as,

[0213] 1) Index is the timeslot number where the multi-slot transmission is located;

[0214] 2) Index is the number of the SBFD symbol within the time slot range where the multi-slot transmission is located;

[0215] 3) Index is the number of the uplink symbol within the time slot range where the multi-slot transmission is located;

[0216] 4) Index is the number of repeated transmissions;

[0217] 5) Index is the relative number of the time slot where the multi-slot transmission is located, and the index starts from 0;

[0218] 6) Index is the number of the SBFD configuration period;

[0219] 7) Index is the number of the time division duplex (TDD) configuration period.

[0220] The following example illustrates a process in which a terminal determines a frequency hopping indication on an SBFD symbol and a frequency hopping indication on an uplink symbol according to frequency hopping related information indicated by a network device.

[0221] The network device sends frequency hopping indication information to the user equipment (UE) through radio resource control (RRC) signaling, downlink control information (DCI) or random access response (RAR), and the UE receives the frequency hopping indication information sent by the network device. If the frequency hopping indication information sent by the network device does not enable frequency hopping, frequency hopping is not enabled on all uplink symbols (or called uplink symbols) and SBFD symbols; if the frequency hopping indication information sent by the network device enables frequency hopping, frequency hopping is enabled on all uplink symbols; whether frequency hopping is enabled on SBFD symbols can be determined based on one or more of the following information:

[0222] a: Frequency domain resource allocation information / configuration information on SBFD symbols, which may include the starting RB and / or the number of RBs;

[0223] b: Uplink subband information, which may include the starting RB of the uplink subband and / or the number of RBs occupied by the uplink subband;

[0224] c: Frequency offset of frequency hopping.

[0225] The above information may be sent by the network device to the UE via RRC, System Information Block 1 (SIB1) and / or DCI.

[0226] Specifically, any of the following methods may be used to determine whether frequency hopping is enabled on the SBFD symbol:

[0227] Mode 1: If the number of RBs corresponding to the frequency domain resources allocated on the SBFD symbol is greater than (or ≥) the threshold value K1, frequency hopping on the SBFD symbol is not enabled; otherwise, frequency hopping on the SBFD symbol is enabled.

[0228] For example, K1 is the number of RBs corresponding to the uplink subband / 2. When the number of RBs corresponding to the frequency domain resource allocation on the SBFD symbol is greater than (or ≥) the number of RBs corresponding to the uplink subband / 2, frequency hopping on the SBFD symbol is not enabled. Otherwise, frequency hopping on the SBFD symbol is enabled.

[0229] Mode 2: If the frequency domain position determined according to the starting RB calculation formula 1 or formula 2 is within the UL subband range, frequency hopping on the SBFD symbol is enabled; otherwise, frequency hopping on the SBFD symbol is not enabled.

[0230] For example: the UE determines that the frequency domain position of each hop is within the uplink subband range based on the starting RB position indicated by the resource allocation information and the starting RB position of each hop determined by formula 1 or formula 2, as well as the length of the RB indicated by the resource allocation information. In this case, frequency hopping on the SBFD symbol is enabled; otherwise, frequency hopping on the SBFD symbol is not enabled.

[0231] Mode 3: If the actual frequency offset between the two starting RBs determined by starting RB calculation formula 1 or formula 2 is greater than the threshold value K2, frequency hopping is enabled on the SBFD symbol; otherwise, frequency hopping is not enabled on the SBFD symbol.

[0232] For example, the threshold K2 is the number of RBs corresponding to the uplink subband / 2. The UE determines the starting RB positions of the two hops based on the starting RB position indicated by the resource allocation information and Formula 1 or Formula 2. If the actual frequency offset between the starting RBs of the two hops is greater than the number of RBs corresponding to the uplink subband / 2, frequency hopping on the SBFD symbol is enabled; otherwise, frequency hopping on the SBFD symbol is not enabled.

[0233] Mode 4: If the conditions in Mode 2 and Mode 3 are met at the same time, frequency hopping on SBFD symbols is enabled; otherwise, frequency hopping on SBFD symbols is not enabled.

[0234] In this embodiment, the terminal can determine the frequency hopping parameters of two symbol or time slot types based on a set of frequency hopping indication information configured by the network device, without increasing signaling overhead, and can reduce the implementation complexity of the network device, increasing the flexibility of the frequency hopping configuration and the frequency hopping gain.

[0235] As an optional embodiment, the terminal determines, according to the frequency hopping related information, a frequency offset for frequency hopping on an SBFD symbol and a frequency offset for frequency hopping on an uplink symbol, including at least one of the following:

[0236] Determining that the frequency offset on the uplink symbol is the frequency offset of the frequency hopping indicated in the frequency hopping related information, and determining the frequency offset on the SBFD symbol according to a first rule;

[0237] The frequency offset on the SBFD symbol is determined to be the frequency offset of the frequency hopping indicated in the frequency hopping related information, and the frequency offset on the uplink symbol is determined according to a second rule.

[0238] In this embodiment, the terminal can determine the frequency offset for the SBFD symbol and the frequency offset for the uplink symbol based on the frequency hopping related information sent by the network device. If the frequency offset indicated by the network device is applied to the uplink symbol, the frequency offset for the SBFD symbol is determined based on a first rule. If the frequency offset indicated by the network device is applied to the SBFD symbol, the frequency offset for the uplink symbol is determined based on a second rule.

[0239] Optionally, the first rule includes at least one of the following:

[0240] (a) determining a frequency offset on an SBFD symbol according to the frequency offset of the frequency hopping, the uplink BWP bandwidth, and the uplink subband bandwidth indicated in the frequency hopping related information;

[0241] Optionally, determining a frequency offset on a SBFD symbol according to a frequency offset of the frequency hopping, an uplink BWP bandwidth, and an uplink subband bandwidth indicated in the frequency hopping related information;

[0242] The frequency offset on the SBFD symbol is determined by the following formula:

[0243]

[0244] or

[0245] M is the frequency offset of the frequency hopping indicated in the frequency hopping-related information. The units of frequency offset M, uplink BWP bandwidth, and uplink subband bandwidth are RBs. The uplink BWP is the uplink BWP for frequency hopping transmission or the currently activated UL BWP. The uplink BWP bandwidth represents the number of RBs occupied by the uplink BWP, and the uplink subband bandwidth represents the number of RBs occupied by the uplink subband.

[0246] Optionally, the frequency offset on the SBFD symbol may also be expressed as: represents the rounding down of the calculation result; or the frequency offset on the SBFD symbol can also be expressed as: Indicates rounding up the calculation result.

[0247] (b) when the activated uplink BWP bandwidth is less than the third value, the frequency offset on the SBFD symbol is the frequency offset corresponding to the first index; when the activated uplink BWP bandwidth is greater than or equal to the third value, the frequency offset on the SBFD symbol is the frequency offset corresponding to the second index; the first index and the second index are related to the index corresponding to the frequency offset of the frequency hopping indicated in the frequency hopping related information.

[0248] Optionally, the first index is: mod(X+1, 2);

[0249] The second index is: mod(X+Q, 4);

[0250] Here, X is the index corresponding to the frequency offset of the frequency hopping indicated in the frequency hopping related information; and the value of Q is 1, 2, or 3.

[0251] In this embodiment, the third value may be a preset or predefined value, such as 50 RBs. When the frequency offset configured by the network device is applied to uplink symbols, if the active uplink BWP (active UL BWP) bandwidth is less than 50 RBs, the frequency offset value on the SBFD symbol is the value corresponding to the index mod(X+1, 2). If the active BWP bandwidth is greater than or equal to 50 RBs, the frequency offset value on the SBFD symbol is the value corresponding to the index mod(X+Q, 4), where Q = 1, 2, or 3.

[0252] As an optional embodiment, the second rule includes at least one of the following:

[0253] (a1) determining a frequency offset on an uplink symbol according to the frequency offset of the frequency hopping, the uplink BWP bandwidth, and the uplink sub-band bandwidth indicated in the frequency hopping related information;

[0254] Optionally, determining the frequency offset on the uplink symbol according to the frequency offset of the frequency hopping, the uplink BWP bandwidth, and the uplink subband bandwidth indicated in the frequency hopping related information includes:

[0255] The frequency offset on the uplink symbol is determined by the following formula:

[0256]

[0257] or

[0258] M is the frequency offset of the frequency hopping indicated in the frequency hopping-related information. The units of frequency offset M, uplink BWP bandwidth, and uplink subband bandwidth are RBs. The uplink BWP is the uplink BWP for frequency hopping transmission or the currently activated UL BWP. The uplink BWP bandwidth indicates the number of RBs occupied by the uplink BWP, and the uplink subband bandwidth indicates the number of RBs occupied by the uplink subband.

[0259] Optionally, the frequency offset on the uplink symbol may also be expressed as: represents the rounding down of the calculation result; or the frequency offset on the uplink symbol can also be expressed as: Indicates rounding up the calculation result.

[0260] (b1) When the activated uplink BWP bandwidth is less than a third value, the frequency offset on the uplink symbol is the frequency offset corresponding to the first index; when the activated uplink BWP bandwidth is greater than or equal to the third value, the frequency offset on the uplink symbol is the frequency offset corresponding to the second index; the first index and the second index are related to the index corresponding to the frequency offset of the frequency hopping indicated in the frequency hopping related information.

[0261] Optionally, the first index is mod(X+1, 2); the second index is mod(X+Q, 4);

[0262] Here, X is the index corresponding to the frequency offset of the frequency hopping indicated in the frequency hopping related information; and the value of Q is 1, 2, or 3.

[0263] In this embodiment, the third value may be a preset or predefined value, such as 50 RBs. When the frequency offset of the frequency hopping indicated by the network device is applied to the SBFD symbol, for an active uplink BWP (active UL BWP) bandwidth less than 50 RBs, the frequency offset value on the uplink symbol is the value corresponding to the index mod(X+1, 2). For an active BWP bandwidth greater than or equal to 50 RBs, the frequency offset value on the uplink symbol is the value corresponding to the index mod(X+Q, 4), where Q = 1, 2, or 3.

[0264] The following example illustrates a process in which a terminal determines the frequency offset of frequency hopping on SBFD symbols and the frequency offset of frequency hopping on uplink symbols according to the frequency hopping related information indicated by the network device.

[0265] The network device and the UE determine the frequency offset for frequency hopping in a predefined manner; or the network device sends frequency offset information for frequency hopping to the UE through RRC signaling or DCI, the UE receives the frequency offset information, and determines the frequency domain offset on the SBFD symbol and the frequency domain offset on the uplink symbol based on the frequency offset information. The UE determines the frequency domain offset based on the frequency offset information configured by the network device, further comprising: determining a frequency offset set based on RRC signaling, determining an index in the frequency offset set based on the frequency offset information, and determining the frequency offset based on the frequency offset set and the index.

[0266] The UE determines the frequency offset of the SBFD symbol and the uplink symbol based on the frequency offset configured by the network device. The specific method can be any of the following:

[0267] Method a: The frequency offset M configured by the network device is applied to all uplink symbols. The frequency offset of the SBFD symbol is or Alternatively, the frequency offset value M configured by the network device is applied to the SBFD symbol, and the frequency offset on all uplink symbols is or The unit of the frequency offset M, the uplink BWP bandwidth and the uplink sub-band bandwidth is RB, and the uplink BWP is the uplink BWP where the frequency hopping transmission is located or the currently activated UL BWP.

[0268] For example, the frequency offset M configured by the network device is 20 RBs, the UL BWP bandwidth is 200 RBs, and the UL sub-band bandwidth is 50 RBs. According to the above method, the frequency offset of the full uplink symbol is 20 RBs, and the frequency offset of the SBFD symbol is Alternatively, the frequency offset of the SBFD symbol is 20 RBs, and the frequency offset of the full uplink symbol is

[0269] Method b: The frequency offset value M configured by the network device is applied to the full uplink symbol (or SBFD symbol). For the active UL BWP bandwidth less than 50 RBs, the frequency offset value on the SBFD symbol (or full uplink symbol) is the value corresponding to the index mod (X+1, 2), where X is the index corresponding to the frequency offset value M indicated by the DCI; for the active BWP bandwidth greater than or equal to 50 RBs, the frequency offset value on the SBFD symbol (or full uplink symbol) is the value corresponding to the index mod (X+Q, 4), where Q = 1 or 2 or 3, and X is the index corresponding to the frequency offset M indicated by the DCI.

[0270] For example, the frequency offset value M configured by the network device is applied to all uplink symbols. When the active UL BWP bandwidth is less than 50 RBs, the index corresponding to the frequency offset value M is index = 0. Then, the frequency offset value on the SBFD symbol is the frequency offset value corresponding to the index mod(X+1, 2) = mod(0+1, 2) = 1.

[0271] For example, the frequency offset value M configured by the network device is applied to the SBFD symbol. When the active UL BWP bandwidth is less than 50 RBs, the index corresponding to the frequency offset value M is 1. Then, the frequency offset value on all uplink symbols is the frequency offset value corresponding to the index mod(X+1, 2)=mod(1+1, 2)=0.

[0272] For example, the frequency offset value M configured by the network device is applied to all uplink symbols. When the active UL BWP bandwidth is greater than 50 RBs, the frequency offset value M corresponds to index = 0, Q = 2, and the frequency offset value on the SBFD symbol is the frequency offset value corresponding to index mod(index+2, 4) = mod(0+2, 4) = 2.

[0273] For example, the frequency offset value M configured by the network device is applied to the SBFD symbol. When the active UL BWP bandwidth is greater than 50 RBs, the frequency offset value M corresponds to index = 1, Q = 3, and the frequency offset value on all uplink symbols is the frequency offset value corresponding to index mod(index+3, 4) = mod(1+3, 4) = 0.

[0274] In this embodiment, the terminal can determine the frequency offset parameters of two types of symbols or time slots based on a set of frequency offset information configured by the network device, without increasing the signaling overhead, and can reduce the implementation complexity of the network device, thereby increasing the flexibility of the frequency hopping configuration and the frequency hopping gain.

[0275] As an optional embodiment, the receiving frequency hopping related information sent by the network device includes:

[0276] receiving downlink control information DCI for scheduling a physical uplink shared channel PUSCH, where the DCI carries the frequency hopping related information; the frequency hopping related information includes frequency offset information of the frequency hopping;

[0277] The method further comprises:

[0278] The length of the first field in the DCI is determined according to the bandwidth of the activated uplink BWP and / or the bandwidth of the uplink subband, where the first field is used to indicate the frequency offset information of the frequency hopping.

[0279] In this embodiment, the network device may send frequency hopping related information to the terminal through RRC signaling, DCI, or RAR. When the network device sends the frequency hopping related information through DCI, for the DCI for scheduling PUSCH, the DCI for scheduling PUSCH is used to schedule a UE supporting SBFD, and the DCI includes a first field for indicating frequency offset information. The length of the first field may be determined based on the bandwidth of the activated uplink BWP or the width of the uplink subband.

[0280] Optionally, determining the length of the first field in the DCI according to the bandwidth of the activated uplink BWP and / or the bandwidth of the uplink subband includes:

[0281] When the PUSCH scheduled by the DCI is within the uplink subband range and the bandwidth of the activated uplink BWP or the bandwidth of the uplink subband is less than the fourth value, the length of the first field is 1 bit;

[0282] When the PUSCH scheduled by the DCI is within the uplink subband range and the bandwidth of the activated uplink BWP or the bandwidth of the uplink subband is greater than or equal to the fourth value, the length of the first field is 2 bits.

[0283] In this embodiment, the fourth value may be a preset value or a predefined value, such as 50 RBs. If the uplink resource scheduled by the DCI is within the UL subband range, the length of the first field may be determined based on the activated uplink BWP or uplink subband. Taking the fourth value of 50 RBs as an example, when the width of the uplink activated BWP is less than 50 RBs, the length of the first subband is set to 1 bit, indicating one of the two higher-layer configured frequency offsets. When the width of the uplink activated BWP is greater than or equal to 50 RBs, the length of the first subband is set to 2 bits, and the frequency offset is indicated by the high-order bit or the low-order bit of the 2 bits.

[0284] Optionally, the DCI further includes a second field, where the second field is used to indicate that the PUSCH scheduled by the DCI is within an uplink subband range or the scheduled PUSCH is within an activated uplink BWP range.

[0285] In this embodiment, the network device may further use the second field in the DCI to indicate whether the uplink resource currently scheduled by the DCI is within the UL subband range or within the UL active BWP range.

[0286] The following example illustrates a method for determining the length of the field indicating frequency offset information.

[0287] For the DCI for scheduling PUSCH, the DCI for scheduling PUSCH is used to schedule UE supporting SBFD, and the length of the first field for indicating the frequency offset of frequency hopping in the DCI is determined according to the bandwidth of the uplink activated BWP.

[0288] Optionally, no matter whether the PUSCH scheduled by the DCI is within the UL subband range or within the uplink activated BWP range, the length of the first field is determined according to the activated uplink BWP.

[0289] Specifically: when the width of the activated uplink BWP is less than 50 RBs, the length of the first field is 1 bit, indicating one of the two frequency offsets configured by the higher layer; when the bandwidth of the activated uplink BWP is greater than or equal to 50 RBs, the length of the first field is 2 bits, indicating one of the four frequency offsets configured by the higher layer.

[0290] Optionally, when the PUSCH scheduled by the DCI is within the UL subband range, the length of the first field is determined according to the activated uplink BWP. For example, when the bandwidth of the activated uplink BWP is greater than or equal to 50 RBs and the bandwidth of the UL subband is less than 50 RBs, the length of the first field is 2 bits.

[0291] Optionally, for the DCI scheduling PUSCH, the DCI scheduling PUSCH is used to schedule UE supporting SBFD. When the PUSCH scheduled by the DCI is within the UL subband range, the length of the frequency offset indication field of the frequency hopping in the DCI is determined according to the bandwidth of the uplink subband.

[0292] For example, when the width of the uplink subband is less than 50 RBs, the length of the first field is 1 bit, indicating one of the two frequency offsets configured by the higher layer;

[0293] When the bandwidth of the uplink subband is greater than or equal to 50 RBs, the length of the first field is 2 bits, indicating one of the four frequency offsets configured by the higher layer.

[0294] Optionally, the network device may indicate, through an indication field in the DCI, whether the uplink resource currently scheduled by the DCI is within the UL subband range or within the UL active BWP range.

[0295] In this embodiment, the terminal determines the length of the field used to indicate the frequency offset according to the bandwidth of the BWP and / or the bandwidth of the uplink subband.

[0296] In an embodiment of the present disclosure, a terminal can determine frequency hopping parameters for two time slot types, namely, SBFD time slots and uplink time slots, based on a set of frequency hopping related information indicated by a network device. This reduces the implementation complexity of the network device and increases the flexibility of the frequency hopping configuration and the frequency hopping gain without increasing the signaling overhead.

[0297] As shown in FIG2 , an embodiment of the present disclosure further provides a method for determining frequency hopping information, which is applied to a network device and includes:

[0298] Step 201: The network device sends frequency hopping related information to the terminal, where the frequency hopping related information is used by the terminal to determine whether to enable frequency hopping and / or a frequency offset of frequency hopping on SBFD symbols, and to determine whether to enable frequency hopping and / or a frequency offset of frequency hopping on uplink symbols.

[0299] The frequency hopping related information indicates whether frequency hopping is enabled and / or frequency offset information of the frequency hopping.

[0300] The frequency hopping-related information sent by the network device may include indication information on whether frequency hopping is enabled and / or frequency offset information for the frequency hopping. The terminal determines whether frequency hopping is enabled on SBFD symbols and / or the frequency offset information for the frequency hopping on the SBFD symbols, and the terminal determines whether frequency hopping is enabled on uplink symbols and / or the frequency offset information for the frequency hopping on the uplink symbols.

[0301] The frequency hopping related information can be used to indicate whether frequency hopping is enabled, for example, if the frequency hopping related information includes 1, it indicates that frequency hopping is enabled; if the frequency hopping related information includes 0, it indicates that frequency hopping is not enabled. The reverse is also possible, and the specific indication method is not limited here.

[0302] It should be noted that the SBFD symbols in the embodiments of the present disclosure may also be replaced with SBFD time slots, wherein the SBFD time slots are time slots in which all or part of the symbols are SBFD symbols, and the uplink symbols may also be replaced with uplink time slots, i.e., the network device determines the frequency hopping-related information in the SBFD time slots and the frequency hopping-related information in the uplink time slots. The embodiments of the present disclosure may be applied to multi-slot PUSCH transmission, PUSCH repeated transmission, and / or PUSCH configuration transmission, etc., without limitation to the specific application scenario.

[0306] The length of the first field in the DCI is determined according to the bandwidth of the activated uplink BWP and / or the bandwidth of the uplink subband, where the first field is used to indicate the frequency offset information of the frequency hopping.

[0307] In this embodiment, the network device may send the frequency hopping related information to the terminal through RRC signaling, DCI, or RAR. When the network device sends the frequency hopping related information through DCI, for the DCI for scheduling PUSCH, the DCI for scheduling PUSCH is used to schedule a UE supporting SBFD, and the DCI includes a first field for indicating frequency offset information. The length of the first field may be determined according to the bandwidth of the activated uplink BWP or the width of the uplink subband.

[0308] Optionally, determining the length of the first field in the DCI according to the bandwidth of the activated uplink BWP and / or the bandwidth of the uplink subband includes:

[0309] When the PUSCH scheduled by the DCI is within the uplink subband range and the bandwidth of the activated uplink BWP or the bandwidth of the uplink subband is less than the fourth value, the length of the first field is 1 bit;

[0310] When the PUSCH scheduled by the DCI is within the uplink subband range and the bandwidth of the activated uplink BWP or the bandwidth of the uplink subband is greater than or equal to the fourth value, the length of the first field is 2 bits.

[0311] In this embodiment, the fourth value may be a preset value or a predefined value, such as 50 RBs. If the PUSCH scheduled by the DCI is within the UL subband range, the length of the first field may be determined based on the activated uplink BWP or uplink subband. Taking the fourth value of 50 RBs as an example, when the width of the uplink activated BWP is less than 50 RBs, the length of the first subband is set to 1 bit, indicating one of the two higher-layer configured frequency offsets. When the width of the uplink activated BWP is greater than or equal to 50 RBs, the length of the first subband is set to 2 bits, and the frequency offset is indicated by the high-order bit or the low-order bit of the 2 bits.

[0312] Optionally, the DCI further includes a second field, where the second field is used to indicate that the PUSCH scheduled by the DCI is within an uplink subband range or the scheduled PUSCH is within an activated uplink BWP range.

[0313] In this embodiment, the network device may further use the second field in the DCI to indicate whether the uplink resource currently scheduled by the DCI is within the UL subband range or within the UL active BWP range.
